Compress a video by lowering its bitrate. Preview the result and export a smaller MP4 that is easy to share. For smaller dimensions or a trimmed clip, send the result into Resize Video or Trim Video directly from this page. Everything runs locally in your browser using WebCodecs — your file is never uploaded to a server, so it stays private and conversion starts instantly. Need more than one operation? Use the "Continue this clip in" links in the workspace — your edits carry over to crop, trim, resize and compress without re-uploading the file.

Frequently asked questions

- Will quality drop?
- Some quality is traded for size. Preview before exporting and raise the bitrate if it looks too soft.
